Features:1) Pure energy extracted from the ground water2) Extremely efficient3) The energy performance of the water-to-water heat pump models setsstandards. The ratio of the free environmental energy gained and theelectric energy input is extremely favorable4) WOTECH offers the new generation of water-to-water heat pumps. The compactWOTECH heat pumps ensure powerful and comfortable heating in a minimumof floor space. Heating capacities of up to 27 kW can be produced usingground water of nearly all quality levels. This means that the sturdiness ofthe WOTECH devices sets new standards. An innovative spiral-type heatexchanger made of corrosion-resistant stainless steel, with even its solderseams sealed, ensures permanent operational reliability5) Innovative freeze protection6) WOTECH stands for maximum operational safety. The spiral heat exchanger isprotected against local ice formation on the inside due to its special geometry7) Silent cooling8) The ELIWELL cooling controller, available as an accessory, extends thefunctionality of the heat pump controller (manager) by adding the coolingoperating mode. The transfer of the cooling output is effected by a heatexchanger the size of which depends on the desired output and the waterquality9) Integrated heat pump manager with 4 x 20-character LC display, comfortableoperation with 6 keys, menu with plain-text display and diagnosis function10) Highly efficient and quiet-running scroll compressor for the environ-saferefrigerant R407C evaporator for optimal heat transfer via highly efficientspiral-type heat exchanger with its solder seams sealed for optimizedprotection against corrosion and freezing for optimization of cooling circuitto ensure high coefficient of performance11) Insulated flexible hose connection for both heating and well system12) Integrated soft starter for low-noise, smooth compressor start-up andlimiting starting currents to max. 30A13) Vibration isolation of the entire cooling circuit towards the housing in orderto minimize vibrations transmitted into the building14) Space-optimized construction taking up floor space of 500-600mm only15) Brine-to-water heat pumps16) Space-saving design with a footprint of 500 x 600 mm17) Insulated flexible connecting tubes for connection to the heating and brinecircuits18) Integrated heat pump manager with 4 x 20-character LCD screen,comfortable 6-button operation, menu-guidance in plain text as well asdiagnostic function19) Vibration isolation of entire refrigeration circuit20) Integrated soft starter for limiting the starting current to 30A21) Top performance figures22) The economizer installed as standard optimizes the refrigeration circuitand improves the coefficient of performance
